' IMPROVIEMENTIIN STARCHING-MAC'HINES.

Specification forming part of Letters Patent No. 1 74,5 87, dated March'7', 1876;

application filed October 29,1875.

To all whom it may concern:

Be it known that I, LEoPoLD STERNBER- GER, of Philadelphia,Pennsylvania," have invented certain Improvements in Starching-Machines, of which the following is a specification: 2

My invention relates to certain improvements in the starching-machinefor which Letters Patent of the United States were granted to me on the21st day of January, A. D. 1873, N 0. 135,171, the objects of my presentimprovements being to simplify the construction of the said patentedmachine, and to render it more effective.

These objects I attain in the manner which I will 110w proceed todescribe, referencebeing had to the accompanying drawing, in which-Figure 1 is a rear view, in perspective, of my improvedstarching-machine; Fig. 2, a vertical sectional view of the same; andFigs. 3, 4:,iand

I 5, detached views of parts of the machine.

The frame or stand A of the machine has, at the top, the table B, thelatter being divided at or near the center by a transverse partition orbridge, D, attached to or forming part of the frame A. The portion E ofthe table can be raised vertically by means of a treadle, F, actingthrough the medium of the connecting-rod a and guided frame I), thelatter being connected to said portion or bed E of the table by rods 00, arranged neareach end. The depression of the bed E on the releasingthe treadle is insured by springs d, coiled round the bars 0, and actingat the lower ends against the frame I), and at the upper ends againstfixed studs on the frame. In the bed E is formed a concavity ordepression, f, immediately above which is arranged a rubber, G, securedto the outer end of a horizontal shaft, g, arranged to turn in bearingson the upper edge of the bridge D, and provided at its inner end with achambered head, H, to which is adapted the upper end of a rod, h,arranged at its lower end to embrace an eccentric, I, on a horizontalshaft, t", which turns in suitable bearings on the frame, and which isprovided with a fast pulley, J, and loose pulley K. (See Fig. l.)Adjacent to the pulleys J and K is arranged a belt-shifter, L, which isoperated from the frame I) through the medium of a bell-crank lever, M,hung to'a downwardly-projecting arm, N, of the frame, the parts being soarranged that upon the upward movement of the frame b the belt will beshifted from the loose to the fast pulley, and vice versa,when the frameis depressed. The rubber G is of the peculiar construction shown inFigs. 4 and 5, being made in two sections, m and W, hinged together, asdescribed hereafter, the upper section m being attached to the shaft g,and the lower section m carrying the rubbing-shoe n. The lower section mhas a central projection, m provided at each end with a lug or pin, 10,adapted to an opening near the lower end of a plate, 1', secured to thecorresponding end of a central projection, m of the upper section m ofthe rubber.

By this arrangement the lower section of the rubber is retained inposition laterally, but can vibrate vertically at the ends, the pins pserving as pivots. The extent of the vibration is regulated by springs.9, arranged in the present instance at each corner of the rubber.A-sleeve, t, embraces the body of the rubber and prevents the access ofdust or dirt to the interior.

The operation of the above-described machine is as follows: The shirt orother article to be operated upon is first properlyfolded, and, afterbeing dipped in the starching composition, is laid on the depressed bedE. The treadle F is'then depressed, so as to raise the frame I) and bedE, thus bringing the fabric into contact with the rubber G. The sameoperation which caused the elevation of the bed E also causes theshifting of the driving belt from the loose pulley K to the fast pulleyJ-of the shaft '5, so that at the instant the fabric touches the rubberG a rapid vibrating movement is imparted to the same through the mediumof the eccentric I, rod h, and shaft g. The fabric is moved about on thebed E until every portion to be operated upon has been passed betweenthe rubber G and the concavity f of the bed E, when the pressure uponthe treadle F is removed, the bed E depressed, and the belt shifted fromthe fast pulley J to the loose pulley K, so as to stop the vibration ofthe rubber G.

important feature of my present invention, as

The construction of the rubber G forms an I it permits the lower sectionm,during. the

above operation, to'turnon its hinge so that it can yield at the ends toallow the passage loose pulleys J and K, and eccentric I, and theconnectingmod. h.

2. The rubber Gr, made-in two sections", 1' and. m hinged together, andprovided with springs s, substantially as and for the purpose setforth.

3. The combination of the guided frame B, operated by the treadle F,with the bed E, its

pins 0, and springs d, and with thebell-crank lever M and itsbelt-shifter L, all arranged and operating as set forth.

In testimony whereof I have signed my name i to this specification inthe presence of two subscribing witnesses.
